Unit 1 Great scientists Using language Homework If you were Nicolaus Copernicus, would you have hidden your theory for so many years? Discussion As a scientist, one should be brave. But Copernicus was afraid of being attacked by the Christian Church. So he had hidden his theory for so many years. What do you think of this? Agree: 1. He was cautious. if he had published his ideas, he would have been killed just as Bruno who was burned to death because his theory was against the Christian Church. 2. Every time when a new idea appears, there are always rejections. It’s normal. Scientists should have patience to spread their truth. 3. It made no sense for him to publish his theory in a hurry. He was just cautious not coward. He should protect himself first. * * 高二人教新课标版必修五 Listening and speaking 1 What do you know about Qian Xuesen?
